Public bug reported:

When using networks without DHCP enabled and "flat_injected" set to
True, the interfaces template is injected in the associated instances or
included in the config drive metadata.

The template includes the interface name, based on a progressive
numbering (eth0, eth1, etc). In case of multiple nics, there's no clear
way to identify the interfaces in the guest OS if the actual interface
naming differs, this is especially valid for Windows instances.

Since the MAC address (hardware address) assigned to each vNIC
identifies uniquely the interface, providing the mac address during the
template generation solves the issue.
